실험 절차
Under argon, 234.2 g (2.475 mol) chlorodimethyl silane, 500 ml TBME and 1.5 g catalyst 1 were added to 75 g (0.550 mol) tetravinyl silane. The reaction mixture was heated, with vigorous stirring, to 45° C. until an exothermic reaction set in and the temperature rose to 51° C. A mixture comprising 525 g (3.853 mol) tetravinyl silane, 1639.4 g (17.327 mol) chlorodimethyl silane and 940 ml TBME was then added slowly dropwise, wherein care was taken that the reaction temperature did not fall below 50° C. Stirring was then continued for 1.5 hours under reflux, the reaction mixture was cooled to room temperature, the catalyst was filtered off over a frit, and volatile constituents were removed from the colourless solution under vacuum. The product took the form of a white solid. Yield: 2120.8 g (94% of theoretical yield).
